Given orchids in really bad shape -need advice

[murphy48]

I went to a plant sale at someones house to get Cymbidiums. They had some great NOID Cymbidiums so I picked some up. The guy then gave me a bunch of unknown orchids that look really dry and like they had too much sun. Does anyone have any idea what these are and how I can help them?

The first one I think is some type of Onc alliance. This poor thing was potted in soil. It has a mess of roots and as you can see some really really dry and dead PB's.

The next one I have no clue. Its so shriveled up. It does have a lot of new roots growing. Any ideas on what it is and how I should revive it?

He then gave me a bunch of keikies from "poor man's orchids" I have no clue what those are. You can see them in the third picture. Should I just pot them up?

I was also given a Phal with tiny stunted leaves but it has 4 new roots growing! Also a Miltoniopsis that although really light green and dry has some new growths.

Help me save these orchids!
